Russia’s foreign ministry spokesman has denied the report. Maria Zakharova, a spokeswoman for the ministry, on Facebook on Tuesday described the reports as “yet another fake.”

The information was said to have been provided by a U.S. partner through an intelligence sharing arrangement that contained information so sensitive that details have been withheld from allies and tightly restricted within the U.S. government.

Early Tuesday, Trump responded to the reports on Twitter, writing "As President I wanted to share with Russia (at an openly scheduled W.H. meeting) which I have the absolute right to do, facts pertaining ... to terrorism and airline flight safety. Humanitarian reasons, plus I want Russia to greatly step up their fight against ISIS & terrorism."

The White House scrambled to respond to the report Monday night, issuing several statements before sending H.R. McMaster, Trump's national security adviser who participated in the meeting, out to speak with White House reporters.

"At no time were intelligence sources or methods discussed and the president did not disclose any military operations that weren't already publicly known," he said during the White House press conference. "I was in the room. It didn't happen."

Secretary of State Rex Tillerson sent a statement regarding the report:

“During President Trump’s meeting with Foreign Minister Lavrov a broad range of subjects were discussed among which were common efforts and threats regarding counter-terrorism. During that exchange the nature of specific threats were discussed, but they did not discuss sources, methods or military operations.”

Washington Post reported that the United States was not given permission to share the material with Russia. Trump’s relaying of the information could risk cooperation with an ally that has access to inner workings of ISIS.

Dina Powell, White House deputy national security adviser for strategy, who also attended the meeting, said: "This story is false. The president only discussed the common threats that both countries faced," in a statement provided by Spicer.

Since Trump’s reveal to Russia, the White House has been trying to fix the situation by contacting the CIA and the National Security Agency.

A U.S. official familiar with the matter said that Trump has “revealed more information to the Russian ambassador than we have shared with our own allies.”

The incident is said to have occurred when Trump welcomed Russian Foreign Minister Sergei Lavrov and Ambassador Sergey Kislyak into the Oval Office last week.

While Trump did not reveal the method in which the intelligence was gathered, he did discuss aspects of the threat that the United States only learned through the espionage capabilities of a key partner.

Trump is said to have described how the Islamic State was pursuing elements of a specific plot and how much harm that an attack of that magnitude could cause. An official also said that Trump revealed the city in the Islamic State’s territory where the U.S. intelligence partner detected the threat.
